USDA On The Hunt For Offspring Of BSE-infected Cow
2012-04-26 13:30:59

Lawrence LeBlond for RedOrbit.com After tests this week confirmed BSE (bovine spongiform encephalopathy) in a dead dairy cow from a California farm, the US Department of Agriculture (USDA) went on the manhunt, or cowhunt, for any offspring the dead animal may have had, stating they could also carry the fatal brain-eating disease. But while USDA officials say there is evidence that the disease can be passed on from a mother to their calf, John Clifford, the agency´s chief...

California Mad Cow Case Poses No Threat To Humans
2012-04-25 09:14:40

Lawrence LeBlond for RedOrbit.com The first case of “mad cow” disease in six years has cropped up on a California dairy farm after health and food experts discovered the disease in a dead cow, the US Department of Agriculture (USDA) confirmed on Tuesday. Officials are calling the discovery a stroke of luck because tests are performed on only a small percentage of dead animals that are sent to the transfer facility in Hansford, California. “We randomly pick a number...

Toxic prions in the brain can be detected with self-illuminating polymers. The originators, at Linköping University in Sweden, has now shown that the same molecules can also render the prions harmless, and potentially cure fatal nerve-destroying illnesses. Linköping researchers and their colleagues at the University Hospital in Zürich tested the luminescent conjugated polymers, or LCPs, on tissue sections from the brains of mice that had been...

Consumers Can Be Assured that U.S. Beef Remains Safe WASHINGTON, April 24, 2012 /PRNewswire-USNewswire/ -- The following is a statement by AMI Executive Vice President James H. Hodges: "U.S. beef products are among the safest in the world and USDA's announcement today confirms that the U.S. animal disease surveillance system works to protect our herds and the public. USDA announced today that a dairy cow that died in California has tested positive for BSE. The animal was never...

Prion proteins may be best known for their role in infectious diseases, but not all of them are destructive, new research shows One of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in Science. Researchers at the RIKEN Brain Science Institute show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to drug resistance and cellular adaptation. Their discovery of a yeast prion with these properties...

Computer modeling supports theory that many dementias spread like prion diseases A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging (MRI) to predict the rate of progression and physical path of many degenerative brain diseases, report scientists at the San Francisco VA Medical Center and the University of California, San Francisco. The technique, developed by SFVAMC scientists in collaboration with a team led by Bruce Miller, MD,...

Weill Cornell scientists say the program might help patients manage their disease Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient's brain will suffer from the spread, neuron to neuron, of "prion-like" toxic proteins -- a process they say underlies all forms of...

A University of Alberta research team has discovered that technology commonly used to decontaminate food industry equipment can also rid meat processing plants of lethal microbial material responsible for the human version of the ailment Mad Cow disease. U of A microbiology professors Mike Belosevic and Norm Neumann and engineering professor Mohamed Gamal El-Din demonstrated that infectious proteins found in the brain matter of cattle can be eradicated from water treated with ozone. The...

Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and eventually become "hard-wired" into the genome, contributing to evolutionary change. Prions were first found to produce heritable new traits more than a decade ago in laboratory studies of simple baker's yeast. The key discovery then was that some proteins could...

Select individuals appear to return to play quicker As elbow injuries continue to rise, especially in pitchers, procedures to help treat and get players back in the game quickly have been difficult to come by. However, a newer treatment called platelet rich plasma (PRP) may pose hope, according to researchers presenting their findings at the American Orthopaedic Society for Sports Medicine's Specialty Day meeting in San Francisco. "PRP therapy is a very exciting area of research and a...
